2 Wires Humidity Transmitter – Lutron TR-RH2W

Range : 10 %RH to 95 %RH.
Output : 4 to 20 mA DC.
- 5.6 mA = 10 %RH, 12 mA = 50 %RH
- 16 mA = 75 %RH, 19 mA = 95 %RH
2 wires, both for signal and power supply.
Precision capacitance type humidity sensor.
External zero and span adjustment.
Allow high cable load resistance, transmitter can install far away from the controller/incator.
Protection for the reverse wires connecting.
TR-RH2W can cooperate the “4-20 mA Controller/Alarm/Indicator” CT-2012, then become a humidity controller and the indicating system. The user can control and monitor the humidity value from far away.
